Abstract

651,114. Joint-making packing. BOVING & CO., Ltd., DARLING, W., and KENNELLY, W. Nov. 25, 1948, No. 30596. [Class 122,(iii)] [Also in Group XXIX] Distortable sealing rings f, Fig. 1, in a rotary spherical valve c disposed in a hydraulic line b<SP>1</SP>, b<SP>2</SP> each comprise a rubber cores g, Figs. 3, 5, within a rubber sheath having flanges f with a metal spacer j therebetween. When the pressures on opposite sides of a ring are equal a small clearance is left between the rotor and its casing to enable the rotor to be easily rotated. On removal of the pressure on the downstream side of a ring by manipulation of the valves l, m, n, the appropriate ring is distorted to form a seal. The ring may be secured to the rotor as in, Fig: 3, or the casing as in Fig. 5. The rings may have a rubber core encased in a metal sheath or may be made from bronze having circumferentially split flanges, or the rubber core g may be formed integral with the flanges f<SP>1</SP>.
